6.11 GSA 80/81 SERVO ACTUATOR
The GSA 80/81 Servo Actuator, when mated with the GSM 85(A) Servo Gearbox, drives a single
flight‐control axis of the airplane, or its associated trim. Once installed into the aircraft, the
GSA 8X servo actuator may be easily removed for maintenance, without removing or de‐rigging
the GSM 85(A) servo gearbox. Note that while the GSA 8X is removed, it is recommended to use
the Servo Gearbox Protective Cover (P/N 145‐00807‐00) to cover the opening of the GSM 85(A).
The protective cover is included with the GSM 85(A) unit, and is designed to prevent foreign
objects from falling into the GSM 85(A).
